Test device and test paper

Abstract

A detection device includes a test cassette and a test strip, wherein the test strip is mounted between the upper cover and bottom plate of the test cassette, a positioning column is disposed in the test cassette, and a positioning hole is formed in the test strip. The longitudinal dimension of the positioning hole is basically the same as that of the positioning column, and the transverse dimension of the positioning hole is larger than that of the positioning column. The present invention further provides the test strip with the positioning hole, and through the mutual cooperation relationship of the positioning column in the test cassette and the positioning hole in the test strip, the success rate of mounting the test strip to the test cassette can be improved, and the scrap rate of production of the test strip can be reduced.
